“…A significant positive effect of foliar N applications on increasing the GPC of common and durum wheat has been reported for several irrigated or high rainfall systems (Altman et al, 1983;Ruske et al, 2004;Tea et al, 2007;Varga and Svečnjak, 2006) and in low rainfall environments (Bly and Woodard, 2003;Orcen et al, 2013;Woolfolk et al, 2002). An effect of foliar N fertilizer applications on grain yield has been reported in a few cases, although decreased yields following late urea spraying have been observed in other cases (Barraclough and Haynes, 1995;Peltonen et al, 1991).…”

ABSTRACTe foliar N application at a low rate is a strategy that could be applied by farmers in substitution to the traditional late soil application when there are restrictions on N distribution. e aim of this study was to compare the e ect of late-season N fertilization strategies on wheat (Triticum spp.) quality. Field experiments were set up in two di erent soils, in Northwest Italy. e e ect of N fertilization was evaluated on two common (T. aestivum L.) and two durum wheat (T. turgidum L. var. durum Desf.) cultivars. Late-season N was soil-applied (40 kg N ha -1 ) as ammonium nitrate at heading, or foliar sprayed (5 kg N ha -1 ) at owering, and compared with a control without N fertilization a er the vegetative growth stage. Nitrogen soil application increased grain protein content (GPC) (+15%) for both crops. is fertilization strategy led also to higher test weight (+1.4%), kernel hardness (+14%), dough strength (W) (+42%), and lower tenacity/extensibility ratio P/L (-18%) in the common wheat, and to a lower yellowberry percentage in the durum wheat (-29%). e strategy to apply a foliar N fertilizer at anthesis at a lower rate, although it has a greater cost e ectiveness, led to a less e ective bread-or pasta-making quality enhancement, with an average increase of GPC and W only in the silt loam soil by 5 and 18%, respectively. is strategy could lead to more successful increase of GPC in soils with a probable lower nitrate leaching during the vegetative stages.

“…The optimum timing of N spraying on wheat has shown that post-pollination foliar N leads to the largest grain protein improvement (Bly and Woodard, 2003;Tea et al, 2007;Woolfolk et al, 2002). A positive relationship between N, provided by foliar fertilization at anthesis, and the bread-making quality of flour has been observed Tea et al, 2004).…”

“…Differences of N and S supply in wheat may influence protein content and composition as well as grain characteristics and dough properties (Jahn-Deesbach et al 1970, Moss et al 1981Randall and Wrigley 1986;Sarandon and Gianibelli 1990;Haneklaus et al 1995;Zhao et al 1999;Wooding et al 2000). The current practice of applying large amounts of N fertilizers to cereal crops without considering S requirements is becoming a concern for crop quality (Tea et al 2007). With the increased use of S-free fertilizers in modern cropping systems (De Ruiter and Martin 2001) and the decrease of atmospheric S emissions by industry, S has become a major limiting factor for crop production.…”

Quantitative proteome analysis of wheat gluten as influenced by N and S nutrition

To increase grain quality, optimal nutrient management is desirable. Recently, atmospheric S emissions from industry have decreased leading to reduced grain quality. Fertilization of N primarily affects protein concentration and biomass production while S fertilization affects the fine tuning of storage protein composition. Additionally, high N supply increases the N/S ratio to the extent that the grains could be classified as S-deficient. Although total protein amounts were not changed by the fertilizer treatments, the amounts of individual gluten proteins were altered. High resolution proteomic analysis of S-containing gluten protein fractions demonstrates that under high N supply, low or high S fertilization significantly changed 41 and 66 of the gliadin and the glutenin proteins. In particular, this change may lead to different dough and baking quality. In conclusion, a high N fertilization induces S deficiency together with a change in gluten proteins and a loss of nutritional quality of grains.

“…The agronomic productivity of soybean plants is dependent upon their capacity to partition a significant proportion of assimilates to the seeds, and the economic value of the crop is directly related to the seed composition (Sebastia et al, 2005). But the current practice of applying large amounts of nitrogen fertilizers to crops without considering sulphur requirements is becoming a concern for crop quality (Tea et al, 2007). Sulphur plays a very important role in various plant growth and developmental processes being the constituent of sulphur containing amino acids methionine (21% S) and cysteine (27% S), and other metabolites such as glutathione (Devi et al, 2012).…”
